CoPrA 5 Release | April 2018
CoPrA 5 is a major upgrade. The range of DeviceLink functionalities has been extended with a new Linearization tool, which is included in CoPrA 5 L and higher. New features in Printer and DeviceLink Profiling expanded the black generation and transformed it into the new Color Generation, offering convenient new options like an easy way to select or exclude individual channels for the separation or the visualization of gamut changes in real time. The new algorithm of the SaveInk module now allows even greater ink savings. Overall users will experience a faster startup of the application and users can get all this at competitive package prices.
DeviceLink Linearization optimizes the tone values of primary gradation ramps for any printer and color combination. The goal of Linearization is for adequate differences from white to 100% of primary inks, smoothing of gradation curves and adjustment of primary colors to a defined, reproducible condition.
CoPrA includes the most advanced colorimetric technologies that are not readily available at the RIP level. ColorLogic’s Default calibration method and ISO 20654 (also known as Spot Color Tone Value, SCTV) are supported for Multicolor printing. CoPrA 5’s Linearization also features G7 calibration and the Protect Lights slider for Flexo printing and calibrating on difficult media and printers.
Calculation Modes can be used for CMYK and Multicolor printing with additional options for G7 for CMYK channels of Multicolor printer and ISO 20654 (SCTV) for spot colors.
How to create a Linearization DeviceLink
Print primary ramps on an uncalibrated printer without any color management. There are two ways to get the necessary measurement data for the creation of a Linearization DeviceLink profile:
Measure the test chart and optimize the measurement data using software, such as ColorLogic’s ColorAnt and open the measurement data in CoPrA; or measure data by using CoPrA’s Measure Tool.
Settings can be customized and the curves can be checked directly before creating a DeviceLink. This DeviceLink profile can be used in any workflow for any type of printing process. For example, when printing a profiling test chart on an uncalibrated printer.
ColorLogic ZePrA supports the use of Linearization DeviceLinks as gradation curves. By using this method, linearization can be applied in the workflow like corrections curves in a RIP. When applying corrections in the RIP other curves must be disabled to avoid double corrections.
Gray Balance Modifications
A new feature in the Printer and the DeviceLink module allows adjustment of the Gray Balance. Users can choose between a cooler and warmer gray balance. This is a nice feature when visual adjustments based on personal color preferences are desired even though perfect colorimetric profiles exist. The effects of changed slider settings are shown in the program in the adjacent graphic.
Note: The Gray Balance setting works independently from the Perceptual Rendering making it a perfect fine tuning tool for any chosen ColorLogic rendering. It will only be used for the perceptual rendering of a printer profile. However for DeviceLink profiling it can be used for any rendering including the four standard ICC rendering intents.
Excluding Channels when Separating
This new expert feature allows packaging professionals to define the channels (including Multicolor channels) of a printer or DeviceLink profile to be used when separating data. For example, if a brown chocolate artwork is intended to be printed in CMYK without using any Cyan in the separation, a CMYK printer profile can be created which only uses MYK. These types of profiles avoid unwanted Cyan dots in the separation and the converted artwork would appear visually close to a conversion with a complete CMYK profile. The new feature can be found in the Color Generation tab of the Printer and DeviceLink profiling modules. This function is particularly intelligent for Multicolor profiles as it searches for replacement colors in the Multicolor channels when excluding a channel (e.g. Cyan) which can compensate for the missing channel in the gray balance. The alternatively calculated Multicolor channels are displayed grayed out in the panel Black Point and TAC.
New Gamut Visualization for Printer Profiles
The Printer Profiling module includes a new feature to visualize the effects of the selected color separation and Black Point settings. The Gamut view available in the tab Color Generation visualizes changes of the gamut shape immediately when altering settings and provides a real time preview of the profile gamut to be expected. The user can immediately see how changes in the settings affect the gamut, for example, how a reduction of the Black Width slider or a very late Black Start reduces the ability of a profile to render dark colors. The Gamut Volume is calculated and displayed in Lab volume units allowing the user to easily find the settings that produce the largest gamut (highest number).
New Black Point Options
The Black Point and TAC of a profile are important settings as they define the maximum contrast and depth a profile is able to produce when separating data. We have changed the graphical display of the black point and added number fields for each channel with a colored icon in front of each number field. Editing will be faster, especially if non-standard color combinations are used in Multicolor printing with non-CMYK inks. The colored icons are a guide to the channels used to build the Black TAC. Depending on the selected Black Calculation setting the number fields are either disabled or enabled.Selecting Auto automatically uses all channels to calculate the black point and therefore individual editing of channels is disabled. The Auto mode will not use any Multicolor channels beside CMYK or in general the first four channels for the Black TAC.The mode Balance CMY allows editing of the black channel (or in general the fourth channel) and additional Multicolor channels. Entered Multicolor color values are fixed – like the Max.Black value – and CMY values will be calculated accordingly.
The mode Custom allows editing of all channels.
Note: For Multicolor profiles with more than four channels you can use the extra Multicolor channels for the black generation besides the first four channels (typically CMYK). However, the total area coverage (TAC) cannot exceed 400%. Values for the Multicolor channels can be entered manually when using the settings Balance CMY or Auto and these values will then be used to calculate the Black TAC. Usually it is not necessary to use those channels but sometimes a dark Multicolor channel adds desired contrast and definition. This can easily be checked by viewing the Lab values below the Custom fields. If the addition of a certain Multicolor channel decreases L* while a*b* values are not significantly altered, using this channel can be considered. However, the gray balance will use additional channels as well.
Improved SaveInk Module
The user interface of the SaveInk module has been streamlined and the save ink Methods have been simplified. Now there are only two methods – Easy and Advanced. The Easy method reduces the settings a user needs to define to a minimum but still achieves economical high quality profiles. Only three settings have to be adjusted in the Easy method: the Total Amount of Color, the Ink Saving slider and the exception Preserve 0% Black.
In the Advanced method all settings are enabled making this the preferred method for advanced users. It introduces a new dE-Tolerance slider which allows tremendous ink savings when set to a high tolerance. dE-Tolerance increases the maximum deltaE between the original profile and the SaveInk DeviceLink profile which results in greater ink savings. In contrast, the predefined Settings SaveNeutral, SaveStrong and Maximum use a low tolerance setting of 0.5 deltaE ensuring a very high color and visual accuracy of the profile. However if greater ink savings are desired it can only be done by reducing the visual accuracy, hence a higher dE-Tolerance setting is required. The new Extreme ink saving preset uses a high dE-tolerance.
Note: Users can save on ink even more by using a higher dE-tolerance setting. We recommend to test ink saving profiles with high tolerance settings closely before using them in production.
New Profile Search Feature
Everybody working with lots of ICC profiles on their system knows how hard it can get to find a specific ICC profile in a crowded drop down menu. In CoPrA 5, all profile drop down menus now function as a search field. Simply type in some letters of the desired profile and only those profiles containing these letters will be shown in the drop down menu. This is a feature power users will love. ESC deletes entries on the Mac and the previously selected profile reappears in the list. Under Windows it is sufficient to click elsewhere to delete entries.
Support for two Gamut Extending Colors per Color Section
The principle of ColorLogic’s Multicolor profiling works as follows:
- We support three main chromatic primary colors which should span a large enough gamut encompassing the gray balance. Typically this is CMY but it can be any other reasonable chromatic color combination.
- Black can be added as an optional fourth channel. If black is used it must be the fourth channel.
- Up to two gamut extending colors can be used in between each section of the main primary colors. This new functionality has been added to CoPrA 5 as CoPrA 4 supported only one gamut extending color.
- Following this approach, printer profiles with up to 10 channels could theoretically be created by CoPrA however, from a quality point of view it is not recommended to create profiles with more than 8 channels. Each additional channel increases the profile size exponentially, so that either a very low grid size or an exorbitantly large profile would have to be used.
The standard Multicolor case
If a standard Multicolor color space with CMYK parts is used, the additional inks Green, Orange and Violet extend the gamut in each section of the three primary colors. In between each section of the primary colors one gamut extending color is used making it a color space with 7 colors.
The advanced case
Some new inkjet printers use a Red and an Orange ink in addition to the standard CMYK inks. CoPrA is able to profile such a 6 color printer since Orange and Red are two gamut extending colors of the main primary color section Yellow and Magenta.
Note: Special test charts must be used when working with two gamut extending colors. Currently ColorAnt isn’t able to create such test charts. We have added new Multicolor test charts for those advanced cases which use two additional channels. The test charts are available via the Tools menu (Open Testcharts folder > Testcharts > Multicolor).
Profile Decryption Service (PDS)
This new feature enables the decryption or re-encryption of demo or encrypted ColorLogic profiles and to either transform them to open ICC profiles that can be used by any ICC aware application or to re-encrypt profiles in order to change their serial number. This feature is only available for dealers with a special NFR license and can be found in the Tools menu.
Without a special NFR license the tool is invisible.
Typically, potential clients who would like to test CoPrA will receive either a demo or an SP (Serialized Profiles) license which allows to build encrypted profiles that can be tested and evaluated fully, but only within ColorLogic products. Some clients would like to test a certain profile in their own workflow, either within a RIP or DTP workflow solution or in an image editing tool, before making a purchase decision. To facilitate this process dealers are now able – with the help of the new feature Profile Decryption – to open the desired profile for the client and convert it to an open ICC profile.
Another application case could be a dealer who wants to create a profile for a client using his CoPrA SP license on his computer. This resulted in a profile that would not work with the clients CoPrA SP license on a different computer. The same would be true for a ZePrA configuration using an encrypted profile. To provide a usable profile or ZePrA configuration to the client the encrypted profile needs to be re-encrypted for the other computer to be used by the client. Again, the Profile Decryption tool can be used to re-encrypt that profile for a different target serial number. In this case the client needs to provide his serial number to the dealer and the dealer can simply enter that serial number and re-encrypt that profile to be used by the client. The goal of this tool is to give the dealer more flexibility by facilitating and speeding up response to clients requirements during the testing phase without the need to contact ColorLogic to obtain decrypted or re-encrypted profiles.
Note: All decryption service usages require an active internet connection and all actions are tracked automatically by ColorLogic. This tool is not intended to provide a profiling service for the dealer – this is still not allowed and requires special fees to be payed to ColorLogic for each sold profile. Currently, as a default, 10 tries (opening or re-encrypting one profile is one try) are possible. If more actions are needed dealers need to request another set of tries via firstname.lastname@example.org.
CoPrA 4.2.1 Release | October 2017
- Color reproduction in the highlight areas of DeviceLinks have been improved. Most relevant for print processes which show large differences in tone value increases of highlight areas between the source and target profile, such as flexo printing.
- The calculation of Exceptions in DeviceLink profiling using Gray and 4CLR profiles as well as certain Black Generation modes (like MinK) have been improved.
In the DeviceLink profiling module warnings which occurred when using Exceptions have been optimized and improved. For example, using the exceptions Triplex and Duplex in combination with the black generation mode MinK is not recommended and now results in a warning message.
CoPrA 4.2 Release | October 2017
- From CoPrA version 4.2 forward, ColorAnt 4 and the Measure Tool are included. Detailed information about the Measure Tool can be found here
- Two new Multicolor Modes available for printer and DeviceLink profiling. The Multicolor Mode Strong has been revised significantly. Detailed information on the feature Multicolor Mode as well as the use of its modes can be found in the online help.
- The Highlights feature, for simulating the first printed tone, has been expanded providing two new options for printer profiling and three new options for DeviceLink profiling. Highlights features are available here.
- The maximum value for the Highlights option has been increased from 10% to 20%. (Ticket #170078)
- CoPrA SP (Serialized Profiles) creates encrypted profiles which are valid for the serial number of the licensed dongle or computer. licenses allow the generation of profiles which are valid for further serial numbers and thus can be used on other computers as well. Please contact us for details and availability.
- The calculation of printer profiles using measurement data whose primaries are lighter than substrate white have been improved. Color values that are lighter than substrate white are no longer truncated, therefore better proofs can be created.
- The interface has been improved for multicolor and 4CLR profiles that don’t contain black. Information on Black Generation and Multicolor Mode will now be displayed during printer profiling. Information about the use of Exceptions will now be displayed during DeviceLink profiling.
- A SaveInk license only can now be issued.
- The Predefined settings for TAC (TAC – Limit300 and TAC – Limit220) in the Save Ink module have been changed.
- Profile Manager – the display of curves of multicolor profiles and profiles not composed of CMYK have been optimized. Curves displayed with the correct primary color names.
- DeviceLink module – the calculation of Exceptions for Predefined settings have been improved.
- The Black TAC setting correctly stores the datat in the information tag of printer profiles and will be displayed correctly when imported into CoPrA.
- CoPrA can be started by draging and dropping an ICC profile or by using the Open with in the contextual menu of the operating system (Ticket #170170)
CoPrA 4.11 Release | January 2017
- The user interface now provides improved feedback when calculating. In CoPrA, various calculations are displayed in the user interface, e.g. for the preview of curves of the separation, the black point, or the exceptions for DeviceLinks. When calculations are made, the Next and Back buttons are deactivated and not active until the calculation has been completed. This ensures that no unwanted settings are applied to the profile calculation.
- Profile reports for CMY printer profiles and DeviceLinks with CMY target profile can now be generated.
- A filter for searching CMY profiles has been added to the Profile Manager.
- The Printer Profile and DeviceLink profiling modules, new Settings have been added for profiles without black separation. The screenshot shows the recommended settings (No Black Separation) for a CMYK profile that does not have black in the separation. Such separations are very useful for the pre-press in the packaging sector.
- For DeviceLink creation, the Print-to-Print – No Black Setting is for a CMYK-to-CMYK DeviceLink without a black separation. Note: by default, the exceptions are set appropriately so that no black is generated.
- A serious error in the measurement data correction for RGB printer profiles has been corrected. (Ticket # 177647)
- Errors in the slider for the setting of the Maximum Black in printer profiles have been fixed. The selected setting can be reset. (Ticket # 112546)
- In the DeviceLink module, display errors in the user interface have been fixed with Exceptions and the Automatic Mode.
- A bug that new ICC profiles added to the system while was running and not displayed has been fixed.
Note: The profile lists are only updated if the application is sent to the background and brought to the foreground. It may take up to five seconds for the list to be refreshed. If the application is running all the time while profiles are being added, the profile lists are not updated to prevent unnecessary calls that would slow down the application.
CoPrA 4.1 Release | Jan 2017
- The calculation of the Gray Exception in the DeviceLink module has been improved. For some profile combinations grays are now rendered darker and thus more accurate to four colored gray vs the gray exception setting. (Ticket #138870)

Note: This only refers to SP licenses.
- Fixed minor layout issues in the PDF Profile Report.
- New UPPCT 2.3.4 measuring tool
- The new UPPCT supports a few more languages. It supports now Croatian, Serbian, Bosnian and Czech languages, too. Not all special characters are correctly displayed though.
- Settings for the X-Rite i1Pro 2 instruments for remission and scan readings have been fixed.
- Fixed an issue with wrong measurement data with Konica-Minolta FD-7
- Improved the Barbieri Device Wizard (stability, usability)
- Fixed the bug that UPPCT crashes when trying to switch from the Virtual Device to Barbieri Spectropad
- The new printing references for FOGRA51 and FOGRA52 have been added for comparison purposes.
Note: To use the comparison feature a paid license is needed. Licenses are available from Ugra.
CoPrA 4 Release | March 2016
Updating Printer Profiles
Printer profiles need to be updated when colors change in order to ensure a consistent color reproduction. A printer profile can be updated in just a few steps:
- Print and measure a small reprofiler test chart on the printer to be updated.
- Select the reference profile to be updated and the desired profile settings.
- Calculation of the optimized printer profile.
- Optional: Create a correction DeviceLink profile based on the reference and the updated profile to adjust print data to the color changes.
- Note: Creation of DeviceLinks requires the tool Devicelink Profiling which is included in the packages CoPrA 4 L, XL and XXL.
Automatically Recalculate DeviceLink Profiles
Existing DeviceLink profiles can be adapted to new source or destination profiles using the module Recalculate. This function is useful when an optimized printer profile based on a reference profile has been created using the printer profiling tool Update Profile and all existing DeviceLinks based on that reference profile have to be adapted to the new optimized profile. For the recalculation CoPrA uses the settings of the original DeviceLink profile (the settings that were used when the profile was created) and replaces a currently used profile with a new source or destination profile (depending on the application). If many DeviceLinks need to be adapted to new profiles or many DeviceLink profile combinations emerge the module Recalculate is an effective time saver.
Additional improvements in CoPrA 4
- CoPrA 4 has an improved gamut mapping. Specifically for small, malformed and “strange” color spaces which are more common in industrial applications like textile, ceramics and high speed inkjet. Higher saturated colors and smoother blends providing colors results closer to the original.
- Multicolor profiles have been improved for accuracy, proofing purposes, increasing the gamut and better separations. The Multicolor Mode is Smooth by default (instead of Strong).
- The profile sizes of printer profiles has been optimized. Profiles will be larger in size due to using optimized grid points. This and other changes in the algorithms lead to an increased accuracy of profiles.
Note: Using multicolor profiles with the very large profile size setting may cause issues with certain CMMs and applications. The Image conversion feature or ZePrA Smart Color Server utilize very large profiles.
- The smoothness of CMYK-to-CMYK DeviceLinks has been improved.
- CoPrA 4 is the first ColorLogic universal binary application on the Mac. E.g. the application can run as 32-Bit or 64-Bit with 64-Bit being the default.
- Multithreading support has been added to CoPrA 4. Several profiles can now be calculated simultaneously.
- A new Multicolor Mode has been added for DeviceLinks with the same amount of channels – Preserve the color properties of the source color space. This mode allows for the Exceptions to be applied on all multicolor channels and not only the CMYK channels.
Example: The Exceptions for primariies would maintain all primaries and the secondaries exceptions would maintain combinations of any of two primaries and not only those with CMY combinations.
- Two new filters for searching have been added to Profile Manager for Updated Profiles and Correction DeviceLinks.
- Select a printer profile to be either the source or the target profile for DeviceLinks. For updated profiles an additional option is available that sets the required profiles and settings for building Correction DeviceLinks automatically.
Note: After selecting the profiles, switch to the DeviceLink module to verify settings and to create the DeviceLink.
- Simplified profiling presets for Digital Printers. The Digital Printer preset will automatically check for the best black point and take into account non-subtractive color behaviors automatically.
- Embed Profiles when creating DeviceLinks: Embeds the source and target profile in the DeviceLink. Certain RIP used in production only permit DeviceLinks if source and target profiles are embedded. Helpful in situations where the source and target profiles are not installed on a remote computer.
Note: The file size will be large. Printer profiles are commonly larger in size than DeviceLinks. ColorLogic recommends using this option if one of the two reasons mentioned above apply. ColorLogic applications do not recognize embedded profiles.
- Support of 2CLR, 3CLR, 4CLR profiles in Image Conversion.
- Image Conversion now supports Lab profiles.
- The embedded profile of a loaded images in the Image Conversion feature has been shown in previous versions of CoPrA. The embedded profile will be selected as source profile automatically.
- CoPrA will show demo and serialized profiles in the drop down menus. Demo profiles will only be shown in a demo version of CoPrA and not in NFR or full versions. Serialized profiles (SP versions) – encrypted profiles working with a specific serial number – will only be shown when the serial numbers between profiles and a recent CoPrA version match.
- Manually keying a TAC value in the field under Blackpoint and TAC will not change the Black TAC with negative results. Type in the value and press enter to change the value.
- Importing settings from SaveInk profiles has been improved.
- Creating CMYK profiles from multicolor data has been fix in situations where the GUI was clicked to the background before creating the profile.
- The late Black Start has been improved in DeviceLinks when creating a new separation. The black is not used in lighter values.
- Fixed several quality issues regarding the use of exceptions for DeviceLink profile creation.
CoPrA 3.3 Release | May 2015
Black Generation: Black Point and TAC
The Total Area Coverage (TAC) and the TAC for the black point (Black TAC) can be defined under Black Point and TAC. The Black TAC represents the darkest color value of the profile which is usually identical with the maximum TAC. Overview of Black TAC adjustment Many modern printing systems allow a black point that is generated by with low amount of ink.
Use one license for a Multi-User system
ColorLogic CoPrA 3.3 and ColorAnt 3.01 include a feature to streamline administrating and loading license files for multiple users on the same computer. Macintosh Systems Copy the license file for the ColorLogic applications to the folder:
- Create the folder if it does not exist.
- Check the permissions on the folder
- When the application is launched, by default it will check the location mentioned above by default and load automatically.
Windows Systems Copy the license file for the ColorLogic applications in the following folder: C:\Users\Public\Documents\ColorLogic\LicenseInstall.
- Create the folder if it does not exist.
- Check the permissions on the folder
- When the application is launched, by default it will check the location mentioned above by default and load automatically.
New Profile Report features and profile quality improvements
- The PDF Profile reporting for multicolor printer and DeviceLink profiles has been improved. CoPrA 3.3 adds more accurate visual color previews of ColorLogics’ test images. By applying the methods below, Acrobat will display a more visually accurate report for multicolor or devicelink profiles. The PDF Report test images are converted with the following methods: Lab to perceptual and also relative colorimetric plus black point compensation, images are converted to DeviceN.
- The Spider Web diagram in the PDF Profile Report has been extended to better show the color of the primary and secondary CMYK axises of printer profiles. Multicolor profiles are displayed with the extending colors similar to ColorAnt 3. Colored points and colored lines drawn to the next neighboring primaries.
- Gamut Mapping quality has been improved for lighter color regions specifically for small color gamuts.
- The generation of Multicolor separations of in-gamut process colors have been optimized. In-gamut process colors are located within the gamut of the three main colors (the main colors are often CMY). Adding in-gamut colors is typically not recommended because they are not extending the gamut of a profile. In certain instances these colors are required in production. ColorLogic recommends the Multicolor Mode Strong. The separations of in-gamut colors with this setting generates has been improved over previous versions.
- Note: In-gamut colors are not used with the Multicolor Mode Smooth.
- Black point and gray balance rendering with the Multicolor Mode – Sparse Inks setting has been improved by using CMYK as the Strong and Smooth modes. The results are noticeable most noticeable in the shadow details.
Bug Fixes in CoPrA 3.3
- Crashes in combination of imported profile settings and clicking the Home button have been fixed.
- Several issues importing profile settings have been fixed including issues such as profile settings could not be imported or crashes of the application or wrong display of settings.
- Saving custom profile settings with a custom name using the Save as works without changing settings.
- The error that the CoPrA3 folder under Documents was not created on an initial installation has been fixed. This fixes a subsequent error message appearing when the Preferences dialog opens.
- A general error message appearing in certain cases a PDF Profile Report opening has been fixed.
- We have changed the limit for TAC reduction that CoPrA could use with certain measuremnent data to 275% instead of 300% when using the Black Calculation options Auto or Balance CMY. This improves the black point calculation for several data where the previous limit prevented a better result.
- Several improvements in the generation of Printer and DeviceLink profiles have been carried out. For example works the Max RGB exception in combination with the Multicolor Mode Smooth now as expected. When using Max RGB one channel will be set to 100% to increase saturation.
- The creation of CMYK profiles without any black (K=0%) has been fixed. This will create a CMY separation with no black.
- Issues with the Black Generation Mode MaxK when using a late Black Start have been fixed.
- The Image Conversion feature retains the file format of the image to be converted if possible and does not change it to JPEG as default. In addition the file format will be correctly used when changing to a different format now.
- The index error while using gray profiles in the Image Conversion feature has been fixed.
- Numbers fields are now checked for incorrect entries like characters or numbers exceeding the range of logical input values.
- Profile Manager displays the curves of DeviceLink profiles created by ZePrA’s SmartLink feature.
- The parameter error message when creating a CMYK profile from a 4CLR data set has been fixed.
- Note: In general from nearly any Multicolor data set a CMYK profile can be build using the checkbox Calculate CMYK Profile. This will work with data sets with more than two channels (except RGB). When a data set does not have a black channel it will be regarded as if it would have one to build a CMYK profile.
- Custom channel names for Multicolor defined in ColorAnt 3’s Custom Chart tool are used correctly now when building the profile with CoPrA 3.3.
- Note: When undefined channel names in multicolor data sets from 3rd party tools are used, CoPrA will calculate using the logical channel names from the hue of each channel automatically.
- Incorrect display of IT8 formatted measurement data files provided from third party instruments (e.g. multiline quoted values from Barbieri Gateway) has been fixed. Some small syntax errors certain third party files that prevented CoPrA from opening them have been fixed. CoPrA is more tolerant with such files and will use them.
- A few issues displaying 4CLR test charts and the Multicolor test charts delivered with CoPrA correctly when measuring them with UPPCT have been fixed.
- The error that a profile selected in the Batch Overview feature was not shown in Profile Manager due to blocking filter settings has been fixed. Now filter settings from previous selections in Profile Manager will be deleted.
- An intermittent error for loaded measurement data in the Printer Profiling dialog when using the Fit to width checkbox has been solved.
- The error that the CoPrA splash screen when starting does not disappear any more if UPPCT was started at the same time from within CoPrA has been fixed.
- Some issues with separation curves not updating correctly in the Black Generation tab have been fixed. In addition the displaying error of the vanished filename of measurement data in the Printer Profiling dialog when resizing the dialog has been fixed.
- Using the X button for deleting existing measurement data in the Printer Profiling dialog works again without producing a format error message.
- Minor errors in the Registration dialog have been fixed.
- The Profile Report feature uses the channel names of Multicolor profiles correctly in the Dot Gain section now.
- The TAC for Multicolor DeviceLink profiles is not exceeding the user defined value any more in combination with the Highlights option First Printed Tone from the Exceptions tab.
